In the past, the term instrumentation amplifier (INA) was often misused, referring to the application rather than the device’s architecture. INAs are related to op amps, in that they’re based on the ...

In order for an op amp to output a linear voltage, the input signal must be within the device’s input common-mode range specification (V CM) and the output must be within the device’s output swing ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

As instrumentation amplifiers become less costly, they can provide improved performance in applications that operational amplifiers traditionally served. The op-amp adder in Figure 1 has a few ...
